October 2015 1HaskellADay Problems and Solutions

October 2015

October 29th, 2015: This is a perfect introduction to today's #haskell problem: dynamic predictions http://lpaste.net/6734184072140029952 because cats. And today's #haskell problem has the added benefit of containing the longest epic mid-type-declaration-comment of epic epicness. Epically. ... but what you didn't see for today's #haskell problem is the preparation #fallingasleepoverthekeyboard #again And the 'S' in the anSwer is not for 'S'tatistician, but for geophf waiting for a 'S'uper heroine to give the anSwer http://lpaste.net/8373695753289203712

October 28th, 2015: Today's #haskell problem, we DEFINE WHAT 'AVERAGE' IS! Nope. But we do take on predictive analytics! http://lpaste.net/6882676007984168960 So there's that. And here's the predictions-distributions. One day we'll even do ROC-analysis. Or not. http://lpaste.net/4234314648314183680

October 27th, 2015: For today's #haskell problem we say "HEY! YOU! GET YOU SOME RANDOM, YO!" and then define a random number generator http://lpaste.net/5973373084290252800 A (random) solution (not really) to yesterday's random (really) #haskell problem http://lpaste.net/3547465428253016064

October 26th, 2015: Well, bleh! It only took all day to compose, but here's today's #haskell problem! "Learning R...in Haskell!"http://lpaste.net/2843567468654362624 Okay, that (randomly) hurt! -- one possible solution to this problem is posted at http://lpaste.net/4854130028864077824

October 23rd, 2015: Today's #haskell problem is thanks to Jim Webber's keynote at @GraphConnect is about triadic closurehttp://lpaste.net/2004709237044805632

October 14th, 2015: For today's #haskell problem we look at multiplying matrices, because SCIENCE! http://lpaste.net/2775082411233378304 Today criss-cross is gonna JUMP-JUMP! ... and sauce the apples http://lpaste.net/6379071958448865280 (What this has to do with matrix-multiplication, I do not know)

October 13th, 2015: A rose by any other name would smell as sweet. A matrix-transpose by any other name is still today's #haskell problem http://lpaste.net/7639242339784851456 Today we transpose matrices ... LIKE A GANGSTA! http://lpaste.net/4495861517937278976

October 12th, 2015: We go from eh-matrices to ÜBERMATRICES for today's #haskell problem http://lpaste.net/3386266226073272320 And we übered those matrices at http://lpaste.net/4104557754952187904

October 8th, 2015: We haven't touched Data.Matrix in a while, and it didn't age well. Let's fix this for today's #haskell problem http://lpaste.net/4256620462181711872 Matrices, REBORN! http://lpaste.net/5942967859750633472 (or at least, prenatal, but we'll get there)

October 7th, 2015: So, after all that work making DList Foldable/Traversable/Monadible (eh?) TODAY's #haskell problem relaxes MultiMap http://lpaste.net/2435920706567929856 That MultiMap is now hella-relaxed, yo! http://lpaste.net/8471070633348825088

October 6th, 2015: So YESTERDAY we looked at Foldable. @argumatronic said "Step it up: do Traversable!" So for TODAY'S #haskell problem http://lpaste.net/4868288594713772032 So we WuTang Traversible CLANNEDthat solution! http://lpaste.net/4953464088320540672

October 1st, 2015: Yesterday we made Difference Lists Applicative, for today's #haskell problem we make them monadichttp://lpaste.net/1062399498271064064 So, difference lists are monadic now ... so there's that ... http://lpaste.net/4828960021565931520
